ROTARY PARALLEL ARM LOADER AND SYSTEM ABSTRACT OF THE DISCLOSURE This rotary loader has two vertical posts each with a rotary arm radiating therefrom with a load platform centered an equal distance out on each arm. The arms are coordinated to revolve parallel and move under and lift or lower together to transfer a load such as a cargo container or railway car body separable from its chassis. Each arm supports the end of a load on a pivot or turntable central of the width of the load. The turntables can be connected to form one platform and the pivots be above or below the load. Preferably the turntables are round and on a lobe of equal diameter on the end of each arm with a rubber rimmed disc wheel of slightly larger diameter on the pivot's axis below the arm to guide the arms of the loader to roll between pedestals or rabbets across the car's platform to couple and align the loader and car for transfer. The loader is vehicle mounted to engage stationary cars or load berths. The loader's arms can each have a hook, preferably retractable flush in the rim of the lobe, to be engaged by a hook on a car to couple and move the loader. Each arm is preferably a parallelogram linkage as viewed from a side and its outer link, a load bracket, supported on a wheel on a cam track concentric about the arm's pivot post. The loader with a cooperating-conveyor places containers or car bodies side by side and reloads them back on a train. Car bodies are positioned end to station platform. With this loader, for example, a dining car body can be taken out from the middle of a passenger train and a sleeper or coach added in its place by a second loader without stopping the train.
